How to use CronApp

#$KThe about box
This box tell you about the version and the developer of cronapp.See also: Dialogs

#$KThe setup dialog
This dialogs lets you configure Cronapp. It contains two fields:
One input field where you can specify the interval between scanning the crontab file. Recommended values: if you have got a slow hardisk: 10 otherwise 5.
A checkbox. If you turn this off Cronapp will not scan the crontab file and perform any jobs.
If you press the button "Save" CronApp will save the settings in its initialization-file.

Note: Even if you specify the minute interval to be 10 minutes don't expect that CronApp will scan the crontab file 6 times per hour. CronApp may be delayed of other running applications. The actual scanning interval will be close to, but at least, 10 minutes.

#$KPurpose of CronApp
CronApp is a program which runs in the background (looking at you mouse cursor). After a user-defined time interval CronApp scans a crontab file. This file contains a list of jobs to do on certain times of the hour/day/week/month. When CronApp finds out that it is time to start a job it starts the specified job. The jobs are programs (Windows or DOS).

#$KHow to use CronApp
First:
Make sure that you have specified the DOS-environment variable "TZ". CronApp uses this variable to determine timezone/daylight saving
If TZ is not set (or garbage) cron assumes that the timezone is "EST5EDT" meaning US time (Greenwich mean time + 5), daylight savings on. The format of the contents of the environment variable TZ is:
	zzz[+/-]d[d][lll]
Where:
zzz	Three-character string representing the name of the current time zone. All three characters are required.	
[+/-]d[d]	Required field containing an optionally signed number with 1 or more digits. This number is the local time zone's difference from GMT in hours.
- Positive numbers adjust westward from GMT.
- Negative numbers adjust eastward from GMT.
This number is used in the calculation of timezone.	
lll	Optional three-character field that represents the local time zone's daylight saving time.
- If this field is present, daylight savings are on.
- If this field is absent, daylight savings are off.	

Examples:
	If you live in England you would use "GMT0".
	If you live in Central Europe you would use "CET-1".

You should not specify the daylight savings, because if you do so cron assumes that the MS-DOS time and file time stamps are without daylight savings (A file created 18:00 on 1st of July is stamped 17:00)

Second:
Start CronEdit to create a crontab file.

Third:
Start CronApp. You will have to start CronApp each time you start Windows unless you append 'CronApp' to the 'load=' line in '[windows]' section of your WIN.INI file.

Fourth:
You must have the BetterLook library in order to use any of the Cron programs.

Note: CronApp uses a file called 'lastcron'. This file is empty. CronApp uses it to remember when the last scan of the crontab file was done. If you delete this file CronApp will not perform the jobs which should have been performed between the last time you ran CronApp and the next time you run CronApp. You can modify the date of the file to make CronApp believe that is was run on a different time.
